上海某研发中心集中式空调冷源系统节能改造

Energy efficiency retrofitting for central air conditioning cold source system of a research and development center in Shanghai

针对该工程集中式空调系统由于机组容量配置过大而造成的冷源能量过剩问题进行了改造,使两幢楼原本各自独立的冷源系统在负荷需求量较小时合二为一,即用一幢楼的冷源设备来满足两幢楼的负荷需求,实现了较为节能的供冷方案。投资回报分析结果表明,该方案年平均节省电能8.1%,一年内即可收回投资。

Performs the retrofitting based on the problem of surplus cold source capacity resulted from oversized installed capacity of chillers,which realizes more energy efficient operation of cold sources by integrating the separate cold source systems of two buildings and utilizing the cold source devices of one building to support the two when the cooling load demand is lower.The result of an investment payback analysis indicates that the average electric energy saving rate is 8.1% and the increased investment can be recovered within one year.
